In order to understand the main features of the circulation established by thermal effects in an initially stably-stratified environment, an advanced Lagrangian particle tracking technique (Hybrid Lagrangian Particle Tracking) is employed.
Although a brisk normal circulation was established in all embryos at 36hpf, BDM treatment halted cardiac contraction within 15 min, causing complete absence of circulation.
The results show that natural circulation is established in helium cooling circuit and the TBM can be cooled effectively after loss of off-site power.
The modern global circulation system established in the Miocene and is still active today (Poore et al. 2006; Wright and Miller 1996).
The calculation results showed that the EPRHRs could take away the decay heat from the primary loop effectively, and that the single-phase and two-phase natural circulations were established in the primary loop and EPRHRs loop, respectively.
The calculation results showed that the EPRHRS could take away the decay heat from the primary loop effectively for air cooling condition, and that the single-phase and two-phase natural circulations were established in the primary loop and the EPRHRS loop, respectively.
A carefully designed water circulation system was established in the laboratory to evaluate the accuracy and precision of flow velocity measured by heat-pulse flowmeter in various conditions.
The simulation results show that, a stable natural circulation can be established in the primary cooling system, the current thermal-hydraulic design scheme is feasible, some design features of the cold pool are found that need some reconsideration.
The natural circulation was well established in the primary and passive residual heat removal systems during the transients and was enough to ensure a stable plant shutdown condition after a reactor trip.
